Abstract: The invention relates to a method for the production of plastic skins by pulverizing, wherein a powder is placed on a forming tool and a plastic skin is formed by sintering. A partial area of the forming tool, at least during a first pulverization step, is made inaccessible to the powder by means of a mask with a preferably inflatable sealing edge. The forming tool is provided with a separating web along one edge of the partial area whereon the mask rests during the first pulverization step with the sealing edge. The invention also relates to a corresponding sintering tool and a plastic part which comprises a plastic skin produced according to inventive method of production, on one surface thereof. The inventive method can produce two-color plastic skins, which are usually used as surface decorations, while effectively avoiding scrap.

Abstract: Thermoplastic polyurethane moulding compounds, which contain easy-to-remove byproducts capable of migration and exhibiting a high light fastness, are obtained by the reaction of one or several aliphatic polyols having a molecular weight of 450 to 4000 g/mol and an OH number of 20 to 235, selected from the group polyadipates, polycaprolactones, polycarbonates, polytetrahydrofuran and corresponding copolymers or their mixtures, with l,6-hexamethylene diisocyanate and/or hydrogenated dicyclohexylmethane diisocyanate as well as a chain extender selected from the group 1,5-pentanediol, 1,6-hexanediol, 1,4-cyclohexanediol, 1,4-bis(hydroxymethyl)cyclohexane and bis-(hydroxyethyl)hydroquinone in an equivalence ratios of the 1,6-hexamethylene diisocyanate to the polyol of 1.5:1 to 14.
